Abstract

A steam generator for converting water to steam by the transfer of heat from a heating medium includes two or more water/steam circuits. Each water/steam circuit has at least one evaporator for transferring the heat from the heating medium to the water. A single water/steam drum receives steam or water and steam from the evaporators. A descending pipe has at least one bypass, from which the supply pipes of the respective water/steam circuits branch off, and a venturi device in the area of the bypass. The inlet opening of the supply pipe of at least one water/steam circuit is disposed in the area of diffuser-shaped outlet of the venturi device such that the supply pipe section acts as a dynamic compression pipe in order to increase the pressure of the working medium in this circuit.
